Description

This high-pressure carbon steel 3-piece ball valve is engineered for demanding industrial pipework applications where reliability, safety, and ease of maintenance are essential. The 3-piece body construction allows the valve to be removed from the pipeline for inspection, cleaning, or service without disturbing the surrounding pipework, significantly reducing downtime and maintenance costs.

Featuring a stainless steel 316 ball and full-bore design, ensuring unrestricted flow and minimal pressure drop across the fitting. R-PTFE ball seats provide excellent chemical resistance and dimensional stability at elevated temperatures, while PTFE sealing components deliver a secure, leak-free seal throughout the rated operating range.

With a maximum pressure rating of 82 bar in smaller sizes and an operating temperature range of -25°C to +200°C, this valve is well suited to high-pressure steam, chemical processing, oil and gas, and general industrial service applications. A built-in locking device enables the valve to be secured in the open or closed position, making it particularly appropriate for installations requiring tamper resistance.

Typical Applications

Key Features & Benefits

  • 3-piece Construction: Allows the valve internals to be accessed and serviced without removing the valve ends from the pipeline, minimising maintenance time and reducing installation disruption.
  • Full-bore design: Provides unrestricted flow through the valve, minimising pressure drop.
  • High Pressure Rating: Rated to 82 bar in sizes 1/4" to 1", this valve is capable of handling demanding high-pressure applications in industrial and process environments.
  • Integrated Locking Device: Allows the valve to be secured in the open or closed position, supporting lockout procedures and providing tamper resistance in safety-critical installations.
  • Stainless Steel 316 Ball and Stem: Delivers excellent corrosion and oxidation resistance, ensuring long service life even in aggressive media and high-temperature conditions.
